To all colt-om may concern:

Be it known that i, FREDERICK N. Coo? s citizen of the United States,residing st the city of Providence, in the county of Providence endState of Rhode isienri, have invented certain newond usefui improve--ments in Integrating Devices end Recor ing-Msnometers, of which thefoliowin is s sgecificetion, reference heing had there/into tL-ft)accompanying drawing.

' This invention relates to the com oinc ion of on integra-ti device ands recording manometer, end has for its object to provide an instrumentof simple end prccticsl con- .strnction that will eutometiceily give thesum and total gallons, cubic feet or other convenient units of measure,of the quantity of liquids or gases that has passed through s givenaperture and at the some time record the variation of the flow so thatthe rate at any period may be readily ascertained.

The on sretus is gerticularly adapted to register t e rote of OW througha pipehr tuhe similar in construction to that commoniy known as theVenturi tube, 'described in United States Patent No. 381,373, April 17,1888, and the said device may he octueted by any desirehlemechenisxn,but

ior convenience l have shown two chambers connected to said tube onecommunicsting with the np-strearn or high pressure side the tube, andthe second chamber chmmunieating with the throat or reduced portion ofsaid tube. These chambers communicate with each other, and in each is oiiost supjorted on a column of mercury, said floats losing connectedthrough suitable moorlanisin to operate the integrating mechanism, andalso to move a recording pen over the face of a continuously rotatingrecord sheet.

This invention is fully set forth in this specification and moreparticularlypointed out in the appended claims.

in the drawings: Figure 1 is a front elevation of my integrating andrecording device connected up to e Venturi tube, showing one of thechambers partially in section and the recording device operatingmechanism.

To the upper endotfioat 17 is connected a long rack 20 adapted to engage one alsoconnected a similar rack 22 adapted to en age the opposite side of thegear 23. l on either of the floats is way up the rack extends into itsstand-pipe and when the float is way down the bottom of the same restsupon the lower end of its cylinder.

- At 24 is a disk or driver mounted on the shaft 25 to be rotatedcontinuously by clock work or other convenient mechanism, not shown. Acarriage 26 is mounted on wheels EL -27 to move laterally across theface of said dish 24 on the bar 28. This carriage is provided withrearwardly extending ears 29'29, see Fig. i, through which ears bear mgscrews 3fl-3fi are threaded.

v liotatably mounted in these bearing screws is the small shaft 31 onwhich the contact wheel 32 is fixed. Also mounted on this shaft is thesmall beveled gear 33 which meshes with a similar gear 34, this lattergear being ar-- ranged to drive the hands of the counter 35 by suitablegearing, not shown, through the shaft 36. Above this counter actuatingdisk 24, is a record sheet disk 37, the same being mounted on the shaft38 to be continuously rotated by a clock or other convenient mechanism,not shown. On this disk is nlounted a record sheet 38 which may be ruledor arranged in any-convenient manner, the one shown being divided intotwenty-four equal parts by radial lines, representing the twenty-fourhours of the day, the same is also marked with a plurality of concentriccircles representing a definite number of gallons, or other units ofmeasure which may be adopted.

At 39 is an upwardly extending arm attached at its lower end to thecarriage 26, the upper end of this arm is arranged to receive arecording pen 40.

At is a lmee lever pivoted to the framework at 42. On the outer end ofthe horizontal arm of this lover is a contact roll 43 which engages theedge of the actuating cam' flexible connection 49, if desired, which insome cases may prove an advantage over the knee lever shown in Fig. 1.

It is found in practice. that the sliding of the contact wheel along theface of the rotating plate has a tendenc Y to wear the periphery of thewheel, and t lat it is of ractical advantage to provide means where ythis contact wheel mayfbe pressed a 'ainst the nected at 57 to the bevelgears 33 and 34.

An essential feature of my device is the construction of the contactwheel whereby the same is caused to move more easily across the face ofthe contact plate. This is accomplished by mounting an auxiliary wheel58 in the main contact wheel, the same being set at right angles to saidmain wheel, whereby the periphery of said auxiliary, wheel will come onthe circumferential line of said contact wheel. ln setting thisauxiliary wheel into the contact wheel 1 preferably form an. aperture 59in said whee which communicates with the periphery of the same throughthe slot 60, the auxiliary wheel being mounted on a bracket 61 to setinto said aperture. This bracket may be stamped out of sheet metalhaving ears 62-62 pierced at 63, said ears being adaptedto be sent down.into the form best illustrated in Fig.9, into which the auxiliary Wheelis readily mounted. l have shown a contact wheel with but one auxiliarywheel mounted therein, but any desired number of these auxiliary wheelsmay be located around .the periphery of said. main wheel to facilitatethe movement of the same across the face of the driving plate.

In the operation of this device the liquids or gases flow through thetube 64 in the di rectionof the arrow. The up-stream side of the tube isconnected at 65 by means or" pipe 66 to the cylinder 3, while the throatis connected at 67 by the pipe 68 to the cylinder 2. When there is noflow through the tube the pressure at all points of the tube is, ofcourse, equal and the floats in both cylinders are at the same height.As soon as the flow begins the pressure in the throat is decreased andbecomes less than that at the point 65, therefore the mercury in chamber3 is forced downward by the excess of pressure on this side, raising themercury and float in the opposite chamber a corresponding amount. Asthese floats move one up and one down they act with corresppnding forcethrough their respective racks and gears on. the shaft 13 to rotate theactuating cam 14 in propor-
